Postfix Puppet Module

This module requires Augeas.

Simple usage

include postfix

postfix::config { 'relay_domains':
  ensure  => present,
  value   => 'localhost host.foo.com',
}

Exec paths

In order to not have any path problem, you should add the following line in some globally included .pp file:

Exec {
  path => '/some/relevant/path:/some/other:...',
}

For example:

Exec {
  path => '/bin:/sbin:/usr/sbin:/usr/bin',
}

Examples

postfix::config

Add/alter/remove options in Postfix main configuration file (main.cf). This uses Augeas to do the editing of the configuration file, as such any configuration value can be used.

ensure

A string whose value can be any of 'present', 'absent', 'blank'.
Default: present.
Example: blank.

value

A string that can contain any text to be used as the configuration value.
Default: Undefined.

Create a sasl_passwd hash from a source file

postfix::hash { '/etc/postfix/sasl_passwd':
  ensure  => 'present',

The following code is necessary to make virtual maps work:

include postfix

postfix::hash { '/etc/postfix/virtual':
  ensure => present,
}

postfix::config { 'virtual_alias_maps':

ensure

A string whose valid values are present, absent or directory.

Example: absent.

source

A string with the source of the file. This is the source parameter of the underlying file resource.

The content of the postfix configuration file. This is an alternative to the source parameter. If you don't provide source neither content parameters a default template is used and the content is created with values in the options hash.
Default: undef

path

Path where to create the configuration file.
Default: '/etc/postfix/${name}'

mode

Permissions of the configuration file. This option is useful if you want to create the file with specific permissions (for example, because you have passwords in it).

options

Hash with the options used in the default template that is used when neither source neither contentparameters are provided.
Default: {}
Example:

 postfix::conffile { 'ldapoptions.cf':
   options            => {
     server_host      => ldap.mydomain.com,
